From 5.0 onwards the -agentlib:jdwp option is used to load and specify
options to the JDWP agent. For releases prior to 5.0, the -Xdebug and
-Xrunjdwp options are used (the 5.0 implementation also supports the -Xdebug and -Xrunjdwp options but the newer -agentlib:jdwp option is preferable as the JDWP agent in 5.0 uses the JVM TI interface to the
VM rather than the older JVMDI interface)
